' Loon-SHUTTLE COVER.

Application filed March 8, 1924. Serial No. 697,857.

To all whom it may concern:

Be it known that I, CHARLEs A. RICHARD- SON, a citizen of the UnitedStates, residing at Mansfield, in the county of Bristol and State ofMassachusetts, have invented new and useful Improvements in Loom-ShuttleCovers, of which the following is a specification.

This invention relates chiefly to shuttles used in carpet and rug looms,the yarn-containing chamber of the shuttle being closed at one side ofthe shuttle to confine a loose cop or coiled body of yarn or thread, bya cover composed of an elongated metal strip having a hinge socket atone end engaged With a pintle in the shuttle body to form a hingeconnection, permitting the cover to swing to and from its operativeposition. The socket is an integral part of the cover and is formed bybending or rolling one end portion of the cover.

The shocks or jars attending the stoppage of the shuttle at the oppositeends of its throw in many cases cause crystallization of the metalforming the socket wall, and cause breakage of said wall, resulting inseparation of the socket from the pintle, and displacement of the coverfrom the shuttle, often with disastrous results.

The object of my invention is to provide a socket which is free fromthis objection.

I attain this object by the improved socket construction hereinafterdescribed and claimed.

Of the accompanying drawings forming a part of this specification;-

Figure 1 is a sectional view of a carpetloom shuttle having a cover, thesocket of which embodies the invention.

Figure 2 is a section on line 22 of Figure 1.

Figure 3 is a side view of the cover look ing toward the inner sidethereof, a portion being broken away.

Figure 4 is a fragmentary side view showing one end portion of the coverbefore the socket is formed.

Figure 5 is a section on line 55 of Figure 4.

Figure 6 is a fragmentary side view showing one end portion of the coverafter a part of the socket-forming operation has been performed.

Figure 7 is a section on line 7'7 of Fig- 55 ure 6.

Figure 8 is a section on line 8-8 of Figure 3. p v

Figure 9 is a section on line 99 of Figure 3.

Figures 10 and 11 are side views, showing aportion of the coverandillustrating a modification.

The same reference characters indicate the cover 14 is a strip cut froma sheet of steel of suitable thickness.

In carrying out my invention I provide one end of the shuttle with anintegral socket, adapted to embrace and turn on the pintle 15, andcomposed of a body portion 17 and introverted end portions 18,increasing the thickness of portions of the socket Wall. The introvertedportions are connected with the body portion by necks 19 (Figure 9).

One end portion of the metal strip forming the cover, as first cut froma sheet, may be formed as shown by Figure 4, this por tion includinglongitudinal ears 20 at opposite edges of the cover. Before forming thesocket the ears are bent inward against one side of the cover as shownby Figures 6 and I 7, the metal, being suitably heated to permit thebending operation, without cracking the necks 19, which connect the earswith the body portion of the cover. The portion which includes the earsis then bent or rolled to form the body portion 17 and the introvertedend portions 18 of the socket, said introverted portions being rolledextensions of the cars 20.

It will be seen that in the socket, portions of the cut edges formed bythe operation of cutting the cover from a sheet are at the inner ends ofthe introverted portions 18, and not at the ends of the socket. Fracturedue to crystallization is liable to start at a cut edge and to progresstherefrom, and is not liable to start at either of the necks 19,

the surfaces of said necks being portions of the condensed and hardenedsurface of the original plate. Owing to this fact and to the increasedthickness provided by the introverted portions 18, the socket is freefrom liability to be fractured.

Instead of providing the cover with ears 20, formed as shown by Figure4:, I may form one end of the cover as indicated by dotted lines inFigure 10, and bend its edge portions over as shown by full lines, thusforming tapering ears 20 the wider ends of which are rolled with thebody of the cover to form the socket as indicated by Figure 10.

I claim:

1. A shuttle cover composed of an elongated metal strip, having atoneend an integral hinge socket formed by rolling an end portion of thestrip, and adapted to turn on a pintle in the shuttle body said sockethaving integral introverted portions increasing the thickness of theends of the socket wall.

2. A shuttle cover composed of an elongated metal strip having portionsof its opposite longitudinal edges bent over upon the body of the stripto form ears at one end thereof, the said end and .ears being rolled toform a hinge socket having introverted portions increasingthe thicknessof the ends of the socket, and necks forming the socket ends.

In testimony whereof I have afiixed my signature.

CHARLES A. RICHARDSON.
